We look at the division of 350394 by 64 
The aim is to understand the frequency of 64 in 350394.

Let's proceed to step 1:
3 divided by 64 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 64

Going ahead to step 2:
35 divided by 64 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 64

Advancing to step 3:
350 divided by 64 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 320 from 350, we get 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 64

On to step 4:
The number 64 fits into 303 4 times, leaving a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 256 from 303 and we're left with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 64

Advancing to step 5:
479 divided by 64 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 547.0
Subtract 448 from 479 to get 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 64

Going ahead to step 6:
64 goes into 314 4 times with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 5474.0
The remainder is 58 after subtracting 256 from 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
When dividing 580 by 64, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 5474.9
Subtract 576 from 580 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 64 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5474.9
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 64 fits into 400 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 5474.906
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 64, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 5474.9062
If we take 128 away from 160, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5474.90625
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5474.90625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5474.90625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5474.90625 with a remaining 0.0.
